This EnhancementEngine is responsible for converting the results of NLP processing - as available in the AnalyzedText content part - to RDF and storing them in the metadata of the ContentItem.
To represent those data in RDF the set of Ontologies as described on
will be used.
At the core is the "String Ontology" (see ) that allows to address parts of the content (encoded as URIs) and attach NLP related metadata to it.
For the representation of NLP data the OLIA Ontology (http://nlp2rdf.lod2.eu/olia/) will be used. This should be relatively strait forward as the AnalyzedText content part already uses concepts defined by this ontologies in various enumerations.
